BEND, Ore. — Three children and a teacher were killed at Silver Rail Elementary School in Bend, Oregon on Thursday afternoon when a 16-year-old gunman blasted through the school's secured entrance and opened fire inside. The attack ended not with a police response but with a civilian who witnessed the teenager forcing his way in, made the decision to pursue him, and fatally shot him inside the building. Five people in total were dead by 1:02 p.m. — the four victims and the shooter himself — and two others were rushed to the hospital with critical wounds, leaving a Pacific Northwest city struggling to absorb a tragedy that consumed an entire school day in under three minutes.
